You need three things to win: discipline, hard work and, before everything maybe, commitment. No one will make it without those three. Sport teaches you that.

I find the business world hard.

The marathon always starts after 30K. That's where the problems start. You start without any problems, without any pain. All the pain comes after 30K. Sometimes, it's possible to have pain even in the finger.

What can you do if a part of it is uphill? You can't work out another route. You've just got to run the one they give you. But they tell me London is a nice course. Even the cobbles, I hope, are not very much of a problem for me.

Always, if you win mentally, you can win physically as well.

I always tell young athletes the same thing, 'Wherever you go, whatever you do, what must your top priority be? Running.'

I was the kind of child who worked hard every day with the cows and sheep - I was a very aggressive boy.
